guest operating system ('guest OS') to boot and create containers
inside the guest environment. This package contains the tools to create
guest OS images.

The goal of the ksm throttler daemon is to regulate KSM by dynamically
modifying the KSM sysfs entries, in order to minimize memory
duplication as fast as possible while keeping the KSM daemon load low.");
